Battery seat

Abstract

A battery seat has a base, a positive terminal and a negative terminal. The base has a bottom, a sidewall, a positive terminal seat, a negative terminal seat and a battery cavity. The sidewall, the positive terminal seat and the negative terminal seat are formed on the base, extend up from the base, are connected to each other and form the battery cavity. The positive terminal is mounted on the positive terminal seat. The negative terminal is mounted on the negative terminal seat. Because the sidewall, the positive terminal seat and the negative terminal seat are connected to each other and to the bottom of the base, the battery cavity is strong and robust. Even a significant crack in the sidewall will not degrade the integrity of the battery cavity, and the battery cavity will still hold a battery without letting the battery fall from the battery seat.

1. A battery seat comprising:
 a base having a bottom and an edge; 
 a positive terminal seat formed at the edge of the base and extending up from the bottom of the base; 
 a negative terminal seat formed at the edge of the base opposite to the positive terminal seat and extending up from the bottom of the base; 
 a sidewall formed at the edge of base, extending up from the bottom of the base, connecting to the positive terminal seat and the negative terminal seat, said sidewall having a top inner edge, multiple lips formed separately on the top inner edge and extending radially inward and a recessed accommodating portion defining at least one angled wall; 
 a battery cavity defined on the base inside the sidewall and between the positive terminal seat and the negative terminal seat; 
 a positive terminal mounted on the positive terminal seat having a positive contact and a tab, said positive contact adapted to press against a positive terminal of a battery mounted in the battery cavity, said tab connecting to a top end of the positive contact and facing the battery cavity; said tab being actuable to displace within said recessed accommodating portion against said angled wall for responsive deflection of at least one of said multiple lips; and 
 a negative terminal mounted on the negative terminal seat having a negative contact connecting to the negative terminal, said negative contact being located in the bottom of the base and adapted to press against a negative terminal of the battery mounted in the battery cavity. 
 
   
   
     2. The battery seat as claimed in  claim 1 , wherein the base includes a positive contact recess formed on the bottom of the base, a through hole formed through the bottom of the base and a negative contact recess formed in the bottom of the base, communicating with the through hole in the base and extending radially inward;
 said positive terminal seat includes a contact seat communicating with the positive contact recess of the base and having multiple side edges, said multiple side edges including multiple contact slots formed therein; 
 the negative terminal seat having a contact seat communicating with the through hole in the base and having multiple side edges, said multiple side edges including multiple contact slots formed therein; 
 the positive terminal having a seat extending into the contact slots of the positive terminal seat and securely mounted on the contact seat of the positive terminal seat and connecting to the positive contact of the positive terminal; and 
 the negative terminal having a seat extending into the contact slots in the negative terminal seat and securely mounted on the contact seat of the negative terminal seat and connecting to the negative contact of the negative terminal. 
 
   
   
     3. A battery seat comprising:
 a base having 
 a bottom; 
 an edge; 
 a positive terminal seat formed at the edge of the base, extending up from the bottom of the base and having 
 a contact seat having multiple side edges formed on the contact seat; 
 multiple contact slots formed vertically in the side edges of the contact seat; and 
 a positive contact recess formed at the bottom of the base and communicating with the contact seat of the positive terminal seat; 
 a negative terminal seat formed at the edge of the base opposite to the positive terminal seat, extending up from the bottom of the base and having 
 a contact seat having multiple side edges formed on the contact seat; 
 multiple contact slots formed vertically in the side edges of the contact seat; and 
 a through hole formed inward from the contact seat and through the bottom of the base; 
 a sidewall formed at the edge of the base, extending up from the bottom of the base, connecting to the negative terminal seat and the positive terminal seat and having 
 a top inner edge; and 
 multiple lips formed separately on the top inner edge and extending radially inward, said sidewall having a recessed accommodating portion defining at least one angled wall; 
 a battery cavity defined on the base inside the sidewall between the positive terminal seat and the negative terminal seat and having a negative contact recess formed in the bottom of the base and communicating with and extends radially inward from the through hole in the negative terminal seat; 
 a positive terminal mounted on the positive terminal seat and having 
 a cap securely mounted on the contact seat and extending into the contact slots in the positive terminal seat; 
 a positive contact being resilient, connected to the cap of the positive terminal, extending into the positive contact recess in the base and the battery cavity and having a top end; and a tab connected to the top end of the positive contact and facing the battery cavity of the base, said tab being actuable to displace within said recessed accommodating portion against said angled wall for responsive deflection of at least one of said multiple lips; and 
 a negative terminal mounted on the negative terminal seat and having 
 a cap mounted securely on the contact seat and extending into the contact slots in the negative terminal seat and the through hole; and 
 a negative contact being resilient, connected to the cap of the negative terminal and extending from the through hole toward the negative contact recess in the battery cavity.
